The cone of depression __________ near a well.

Wells: Cone of Depression Pumping from wells lowers the water table near a well. This known as the cone of depression. The land surface overlying the cone of depression is also referred to as the area of influence. Groundwater flow is diverted towards the well as it flows into the depression cone. Wells: Induced Recharge

If faults, fractures, or boundaries are present near the well, the cone of depression will be asymmet­ rical. The cone of depression can be visualized as a series of disks of porous material that change density as the water mass is removed from the pore spaces.Cone of depression The farther away you get from the well, the less effect the pumping has on the level of the water table. It's a gradual change, so the water table level around a well has a sort of cone shape. That is called the CONE OF DEPRESSION. This cone of depression is one of the "valleys" in the water table.Drilling a well near the coast can still tap a freshwater aquifer. Saline aquifers also exist both underneath the oceans and under the land surface. ... (13) A cone of depression occurs when you drop your scoop of ice cream (made with groundwater) on the ground on a hot summer day. Your Answer Correct AnswerThe time rate of lateral growth of the cone is independent of the rate of discharge by the well and depends only on the physical characteristics of the aquifer. The cone must grow laterally much more rapidly in artesian aquifers than it does in nonartesian. The characteristics of the cone in actual aquifers are then considered.
